Well, I can't comment on relating to OSG, but this is usually going to be related to memory overruns. Are you in a debug build? The debug builds have extra padding on allocation (guard regions) that are checked at various times. If the guard regions are damaged, the compiler will warn you, but it's non-fatal because the guard region took the hit instead of your real data. But it is a REAL error, because in a non-debug build your real data would have probably been trashed. Tools like valgrind on Linux might point out the same issue, if it exists on Linux. I'd start by examining code _prior_ to the exception. The exception is telling you the damage has been done, but basically triggers AFTER the offending code. > If any of you feel super-helpful and want to give the project a quick spin: > http://labs.nortd.com/sx/downloads/ > A long guide is here: > http://code.google.com/p/sceneexpression/wiki/GettingStartedOnWindows I do have a favor to ask. Your project is called Scene Expression, and that's kind of uncomfortably close to a tool my company makes called Scene Express: http://www.google.com/search?q=scene+express&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a which incorporates an OSG-based landscape viewer (NatureView Express) and has been around since 2003: http://3dnature.com/history.html Would you mind considering changing the name of your toolkit to something a little more different from my company's product? I'm interested in your project as I have considered doing an OSG application framework myself at times. Yours seems a little different than the goals I wanted to pursue, but it looks very nice for what you're trying to accomplish. > Any hint very much appreciated, > Best, > /stefan -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
